The phrase "as a function of calendar" is not standard in written English and may cause confusion.
It could be used in contexts discussing time-related variables or scheduling, but it is better to clarify the intended meaning.
Example: "The project's timeline will change as a function of calendar adjustments made by the team."
Alternatives: "in relation to the calendar" or "based on the calendar".
The model, in the formalism chosen here, predicts the changing incidence rate I (t) as a function of calendar time t in terms of the transmissibility, denoted β (t, τ ), an arbitrary function of calendar time t and time since infection τ. β (t, τ) typically reflects pathogen load, or perhaps more precisely pathogen shedding.
The model fit to the SEER cancer incidence, the third calibration target, is presented in Figures 3 and 4. In Fig. 3, the age-adjusted EAC incidence rates are plotted as a function of calendar year for both the Model and SEER data; in Fig. 4, the EAC incidence rates are stratified by specific age groups.
We estimate the frequency distribution of the times since infection by modeling HIV incidence and deaths from its prevalence, as a function of calendar time.
Each area represents the range of concentrations for one congener covered by individuals of all ages as a function of calendar time.
The cumulative numbers of observed and expected prostate cancer deaths in this period are shown in figure 1A,B as a function of calendar year from 1970 and age attained from 40 years.
For comparison, the circumcision rate of 20-year-olds as a function of calendar year is plotted in Figure 2, combining data from the present study and the previous one [ 2].
We modeled diabetes prevalence as a function of age, calendar year, and birth cohort, and used our cohort model to estimate age-specific diabetes incidence.
Incidence rates were modelled as a function of age, calendar period and birth cohort, with the central value of the latter calculated by subtracting the midpoint of each age category from the midpoint of the period.
These observations suggest that adenocarcinoma incidence, in contrast to squamous cell incidence, is not well predicted by the risk estimates obtained in the 1960s and that the error in estimation changes as a function of advancing calendar year.
To account for the time-dependent incidence of respiratory syncytial virus, calendar time was adopted as analysis time, which enabled modeling the baseline hazard of infection as a nonparametric function of calendar time (31).
We employed a population PK model that describes changes in body concentration of PCBs as a function of age and calendar time for multiple individuals representing different birth cohorts of the average population (Alcock et al. 2000; Pinsky and Lorber 1998).
